Answer:

-1/4

Step-by-step explanation:

y=x

y=20

x=5

y=_x

20=k(5)

20/5=4

k=4

-1=4(x)

Scientists can estimate the number of bacteria in a refrigerated food using the formula 0.26=

monitta

Time is C. 50 seconds

Step-by-step explanation:

The population of bacteria at time t here is given by

$0.2b=\frac{t^2}{20}$

where

b is the number of bacteria

t is the time in seconds

Here we want to find the approximate time at which the number of bacteria is

b = 625

Substituting into the equation and solving for t, we find:

$t^2=20\cdot 0.2 b\\t=\sqrt{4b}=\sqrt{4\cdot 625}=50 s$

Therefore, the solution is

C. 50 seconds

Is the expression 2f + 4f + 2 – 3 equivalent to 6f – 1? 6f – 1 evaluated at f = 9 is 53. 2f + 4f + 2 – 3 evaluated at f = 9 is a

morpeh [17]

We have that

the expression 2f + 4f + 2 – 3-------> we can group it (2f+4f)+(2-3)
(2f+4f)+(2-3)=(6f-1)
therefore
the expression [2f + 4f + 2 – 3] is equivalent to [6f-1]

if the expression [6f-1] for f=3 is 17
then
the expression [2f + 4f + 2 – 3] for f=3 is also 17

let's check it
[2*3 + 4*3 + 2 – 3]--------> [6+12+2-3]=[20-3]=17------> is ok
